There’s more to it than that. As the leader of the GOP field, Trump is on the other side of the political divide from Jackson, a longtime Democrat who backed President Obama’s presidential campaigns.

But their dispute has its origins in an interview that Jackson gave to Rhapsody, the United Airlines magazine, in which he was asked about golfing with Trump. Who’s the better golfer? “Oh I am for sure. I don’t cheat.”

Jackson also relayed a story about getting a bill from the Trump National Golf Club for membership dues, even though he has not signed up to be a member. As for Trump’s presidential prospects, Jackson said, “More P.T. Barnum than politician. I don’t think he believes half the things he says.”

That didn’t sit well with Trump, who on Tuesday tweeted that he didn’t know Jackson and “to the best of my knowledge haven’t played golf w/ him & think he does too many TV commercials — boring. Not a fan.”

I don’t know @SamuelLJackson, to best of my knowledge haven't played golf w/him & think he does too many TV commercials—boring. Not a fan.

Jackson, however, didn’t let it end there. He appeared on “Late Night with Seth Meyers” on Tuesday, telling Meyers that he’s met Trump “a lot. I’ve played golf with him. I actually played golf with him with Anthony Anderson, we were all playing together, and we saw [Trump] hook a ball into a lake at Trump National in Jersey. And his caddy told him he found it.”

He also relayed a story of Trump calling him personally to play golf.

“When I got there [to the golf course] it was President [Bill] Clinton, who could also verify that Donald Trump knows me,” Jackson added. He said that he and Clinton ended up playing together but Trump did not play that day.

So…

Anderson backed up Jackson’s story in a tweet, while the actor posted to Instagram the bill that he got from Trump National. Meyers, meanwhile, riffed on the idea of Trump criticizing another celebrity for overexposure.

Now it may be a question of who gets the last word.

On Twitter on Wednesday, Trump acknowledged some familiarity with Jackson’s golf game, but he’s not impressed. “I don’t cheat at golf but @SamuelLJackson cheats—with his game he has no choice—and stop doing commercials!”

I don’t cheat at golf but @SamuelLJackson cheats—with his game he has no choice—and stop doing commercials!

Trump may be breaking the conventions of a presidential candidate, as no tiff appears to be too small for him to make into a feud. It is more ink for him, but also for Jackson, who is in the midst of promoting “The Hateful Eight.”

So, we’ve got a debate between somebody who reads scripts, wears costumes, and pretends for a living, and somebody who has developed and amassed a multi-billion dollar collection of properties. Hollywood actors are the LAST people we should consult for guidance on anything. They could not possibly be more detached from reality.﻿

So in less than 24 hours Trump has flip-flopped from claiming he never met Sam L. Jackson, to now having intimate knowledge of Sam’s golf swing. Trump tells so many lies that he can’t keep them all straight.
